N721SF 1976 Learjet 24D (design reference)
- 1976Built
ROUGH RANGE
What N721SF might be worth, and where it’s heading.
A rough range: Radar's value model doesn't cover the Learjet 24D (design reference) on its own yet. From Radar's listing-based estimates for business jets of similar engine thrust and age. The Embraer Phenom 300/300E curve gives the shape of the forecast, and the range is widened to match. Not an appraisal.
